ROBERT EDWIN REARDON, OF CHERRYDALE, VIRGINIA.

DUMMY CARTRIDGE.

Specification of Letters Patent.

Application filed March 13, 1917, Serial No. 154,564. Renewed January 2,1920. Serial No. 349,092.

To all whom it may concern:

Be it known that I, Ronnn'r EDWIN REAR- DON, a subject of the King ofGreat Britain, and a resident of Cherrydale, Virginia, have inventedcertain new and useful Improvements in Dummy Cartridges, of which thefollowing is a full description.

This invention relates to improvements in dummy cartridges for practicerod attachments, and the objects of the invention are to provide asimple and effective form of dummy cartridge for magazine practice withpractice rods.

Further objects are to minimize complete compression of the retractedstrain, and to so construct the cartridges that they may be manufacturedat small cost, and consists essentially of the improved constructionhereinafter described in detail and illustrated in the accompanyingdrawings forming part of the same.

In the drawings,

Figure l is a longitudinal section through a cartridge embodying thepresent invention. Fig. 2 is a cross sectional view.

Referring to the drawings, A represents an outer shell comprising a nose11 shaped to correspond with a bullet of a cartridge and a body portion12 shaped to correspond with the body portion of a cartridge, the shellA, however, is all pressed from a single piece of metal such as sheetmetal, and is screw threaded interiorly at 18 to receive acorrespondingly threaded end cap or plug 14:.

15 represents the striking rod extending longitudinally in the shell Aand adapted to be projected through. the bore 16 in the nose 11. The endof the striking pin opposite to that which projects through the nose hasa pin 17 which extends through a perforation or orifice 18 in the cap14.

The rod is held in normal position and retracted after it has beenprojected forwardly by means of a spiral compression spring. 19 whichabuts a shoulder 20 at the 'inner side of the pin 17, and a collar 21-supported by a sleeve 22 which fits a cylindrical recess 23 in the nosel1 and is securely held therein.

Complete compression of the spring 19 is prevented by means of arms orwings 24 adapted to abut the collar 21 before the spring 19 iscompletely compressed.

The invention is adapted to be used in conjunction with a targetpractice rod, which term designates a spring retracted rodadapted to beprojected from the barrel of a fire arm or the like by means of thehammer or bolt mechanism.

In using the dummy cartridges which form the present invention, the rod15 in Figs. 1 and 2 is adapted to be struck by the hammer or by thespring actuated bolt and thereby projected forwardly to strike thetarget practice rod and propel the same.

It will be seen that by constructing the shell or casing all in onepiece, the cost of manufacturing is reduced, and at the same time, astronger article is produced. Vhen an ordinary unfilled cartridge shellis used, the bullet portion is liable to become detached from the shellproper and this defeet the present invention overcomes.

As many changes could be made in the above description and manyapparently widely different embodiments of my invention within the scopeof the claim constructed without departing from the spirit or scopethereof, it is intended that all matter contained in the accompanyingspecification and drawings shall be interpreted as illustrative and notin a limited sense.

IVhat I claim as my invention is:

A dummy cartridge for target practice rods comprising a casing shapedlike a cartridge, an end cap, a longitudinally extending rod, a pin onthe rod extending through the cap, a tube surrounding the rod on theinterior of the casing, a collar carried by the tube, a spring extendingbetween the collar and the pin on the rod and adapted to retract therod.

In witness whereof I have hereunto set my hand.

ROBERT EDWIN REARDON.
